SPECIFICATION forming part of Letters Patent No. 35 5,416, dated January 4, 1887.

Application filed July 23, 1883. Serial No. 101,620. lNomodel.)

To. all whom it may concern:

Be it known that I, WILLIAM H. H. SIsUM, of Brooklyn, in Kings county, and State of New York, have invented a certain new and useful Improvement in Machines for Unloading orUnbunching Match-Sticks, of which the" following is a specification.

The object of this improvement is to pro-' duce a simple and compact machine for unloading or unbunching match sticks. which have been bunched for the purpose of dipping kmatch-sticks between them on a roller, A.

The shaft or arborA is provided with a spline or feather, and the inside of the roller A with a recess fitting the spline. The roller is slipped on and off the shaft endwise.

The shaft Ais supported in a frame, A", consisting of arms pivoted to the frame 0 and a cross-bar or stretcher connecting them.

The shaft A is clamped to one of the arms of the frame A so that it will not rotate too freely, but will produce a tension on the tapes as they unwind.

- The tape B passes around a roller, D, and

fits within a peripheral groove therein. Before leaving the roller it passes between it and a small regulator-roller, E, whose shaft is supported near one end in a bearing which is pivotally connected to 'the frame, so that it may rock longitudinally. A spring, F, acting on this bearing causes this roller E to press against the tape B as it passes around the roller D, thereby regulating the feed of the tapes. Leaving these rollers, the tape B passes to a roller, G, on which it is wound up. The roller G has an internal recess fitting a spline or feather extending from the shaft G, on which it is mounted.

The tape B passes a shortdistance around the roller D, and then passes in the reverse dito this roller. .with a gear-wheel, L, which is mounted upon rection around a roller, I, which is loosely mounted on a stud, l, and thence to a roller, H, on which it is wound. This roller H has an internal recess fitting a spline or feather extending from the shaft H, on which it is supported. The shafts of the rollers G andH rotate in reverse directions. The said rollers serve to take up the slack of the tapes B B. They turn with their shafts, and can be slipped endwise on and off their shafts.

' J is the driving-shaft of the machine. provided with apulley, J, which has motion transmitted to it by a belt from any suitable source of motion. It is also provided with a pulley, J .which receives a belt, J whereby motion is transmitted to a pulley, J*, on a shaft, K. The belt J may be tightened or slackened to cause it to drive or release the pulley J on the shaft K. i

I have shown a belt-tightener consisting of a bell-crank lever fulcrumed by a pin, a, to the frame 0, carrying at one end a roller, J adapted to act 011 the belt J5, and pivoted at the other end to a rod, J; The rod J is connected at the lower end to one end of a lever,

Itis,

J which is fulcrumed at about the middle of itslength, and at the other end is provided with a foot-piece, which may be acted upon by the attendant of the machine. By depressing the foot-piece the roller J is made to act upon and tighten the belt, and by releasing the foot-piece gravity acts to remove the said roller-from the belt.

The shaft K is provided ono'ne end with' a large gear-wheel, K, and asmaller gear-wheel K which are rigidly affixed to it. The gearwhcel K engages with a gearwheel, H, mounted on the shaft H, on which the roller H is supported, and thereby imparts-motion The gear-wheel K also engages a shaft, L, that is journaled in the frame O. The gear-wheel L engages with a gear-wheel, G which is mounted on the shaft G, whereby the roller ,G is supported. The gear-wheel G and the gear-wheel H are clamped to their rev speetive shafts, so that either the gear-wheel or shaft may slip relatively to the other. The

gear-wheel K engages with a gear-wheel, E, on the shaft of the roller E. The roller E, being thus positively rotated in contact wi h the tape B, draws that tape along, and by the tenmain frame of the machine.

sion of the tape which it produces aids in unwinding the tapes B B from the roller A. This is important, for, owing to the manner in which the'wheels G H are secured to their shafts G H, merely by friction-clamps, they -might prove insufficient to unwind the tapes from the roller A if unaided by other means.

Fig.4 clearly illustrates the manner in which the gear-wheels G H are clamped to the shafts G H. On each shaft is ashoulder, and next to this shoulder fits a disk-shaped clamp, M. Next the clamp M fits the gear-wheel,and next the gear-wheel is another disk-shaped clamp, M. Outside the clamp M is a nut,

M and it fits a screw-tl1read on the shaft. A

jam-nut, M, fits, on the screw-thread of the shaft outside the nut M The clamps have in the sides next the gear-wheels cavities, in which fit paekings of leather or other suitable material.

The shaft A is clamped to the arniof the frame 0 in just the same way that the shafts G H are clamped to the gear-wheels Gr H The match-sticks are longer than the roller D is wide; hence they extend not only over but beyond the edge portions of the said roller which form the sides of its peripheral groove. This groove is just about large enough to accommodate the tape B.

At the sides of the roller D are strippers N, which for a considerable distance are concentric and coincident with the side portions of the said roller. where the tapes are caused to diverge around the rollers D I, these strippers have portions s, which extend in lines tangential to the side portions of the roller D. These tangential portions extend at a downward inclination toward their outer ends, and strip or lift the match-sticks from the roller D and form a chute over which the match-sticks may be discharged. Guards 0, consisting of small rods or wires, extend over these tangential portions .of the strippers, and prevent the match-sticks from escaping therefrom except over the ends. The strippers are fastened by screws to a bar, N, which is secured to the The guards are secured in holes or sockets in the stud I',which supports the roller 1.

It is advantageous to secure the wheels G A machine having friction-clamps applied to the shafts of the bunch or delivery roller Beyond the pointand the take-up rollers may be made much more compact than one in which belts are usedsufficiently slack to slip.

WVhen the tapes are all wound on the takeup rollers G H, the latter are slipped off and placed in a machine wherein match-sticks are bunched for dipping them in the igniting material.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a machine for unloading or unbunching match-sticks, a delivery or bunch roller' for holding tapes, a shaft for said roller connected with its bearings by a friction-clamp, take-up rollers for receiving the tapes, gearwheels connected by friction-clamps with the shafts of said take-up rollers, rollers around and over which said tapes pass and diverge, and a positively-driven regulator-roller acting in conjunction with one of the rollers around which tapes pass at the point of divergence, all being so combined apd organized that the regulator-roller will cause the tapes to be moved at a uniform speed irrespective of the diameters of the portions of the tapes wound upon the delivery or bunch rolleraud the takeup rollers, that the delivery-roller may slip to accommodate itself to the speed of the regulator-roller, and that the take-up rollers will only rotate with a force sufiicient to take up the slack ofthe tapes, and not with a force sufficient to interfere with the proper action of the regulator-roller, substantially as specified.

2. In a machine for unloading or unbunching match-sticks, the combination ofa delivery or bunch roller for holding tapes, a shaft for said roller connected with its bearings by a friction-clamp, takenp rollers for receiving and taking up tapes, gear-wheels connected by friction-clamps with the shafts of said take-
